Assemblyman Nielsen said he plans to run for the newly drawn 3rd District in 2012.

State Sen. LaMalfa has declined to say whether he will seek re-election in 2014.

State Sen. Doug LaMalfa and Assemblyman Jim Nielsen will continue to represent Shasta and Siskiyou counties through the end of 2012. An earlier version of this story incorrectly implied that the lawmakers wouldn't represent the area through the end of that year.

A pair of north state lawmakers assured their constituents in Shasta and Siskiyou counties this week that they'll still have their undivided attention through at least 2012, even though newly approved political boundaries may soon have them campaigning further south.

Assemblyman Jim Nielsen, R-Gerber, and state Sen. Doug LaMalfa, R-Richvale, will continue to represent Shasta and Siskiyou counties through 2012, even though a statewide redistricting commission released maps Monday that put the lawmakers' hometowns in boundaries that have Tehama County as the northernmost part of districts that extend nearly to Sacramento.

If the maps survive legal challenges and a possible referendum, Shasta and Siskiyou counties would be part of the 1st Senate and Assembly districts.

The new districts group Siskiyou and Shasta with counties to the east along the Nevada border.

LaMalfa's spokesman Mark Spannagel said the senator's constituents in the northern part of his current district will continue to see the well-traveled senator, whom he described as a "road warrior," at community get-togethers, even though they'll be represented by someone else at the end of 2012.

Spannagel said LaMalfa would never shirk his duties to his constituents because of the new lines.

"It's just fundamentally not the way Doug operates," Spannagel said. "He'll be everywhere, just the same as he's always been."

After the boundaries shift at the end of 2012, LaMalfa will continue to represent the newly defined 4th Senate District until his term expires in 2014.

At that point, he'll have to run for re-election if he wants to keep his seat.

LaMalfa has declined to say whether he's decided yet to do so, saying he's going to focus on his current term.

On Monday, Nielsen said he'll begin campaigning for the newly drawn 3rd Assembly District for the 2012 elections.

Nielsen issued similar assurances as LaMalfa, his close political ally, that he'll still be looking out for north state interests.

Nielsen, who was a state senator from 1978 to 1990, said he's been through redistricting boundary changes before.

He said that he still has close relationships with constituents who live in boundaries he used to represent.

He said he'll expect the same for Shasta and Siskiyou counties, should he get re-elected.

Meanwhile, Assemblyman Dan Logue, R-Grass Valley, and Sen. Ted Gaines, R-Roseville, whose current districts make up most of the new 1st Assembly and Senate district boundaries, announced Monday they're going to start campaigning in Shasta and Siskiyou counties for the 2012 elections.
